This allows a JWT issued for one Resource Server to be successfully replayed against a completely different Resource Server, leading to Token Confusion/Routing attacks.\u00a0Users are recommended to upgrade to versions 4.2.2 or 4.1.7, which fixes this issue.\n\nCredit:\n\nGuanping Zhang reported this vulnerability.
